I am going to be doing a rear diff fluid change on my 2002 Chevy Silverado 1500 4wd. I know that the ring gears come in 10 1/2" and 9 1/2" sizes. How do I find out which one I have?
Also, if I have a posi rear end is there anything special I have to do when I put in the new fluid?
I am not sure if I have a posi rear end. How will I find out?
Thanks I appreciate your help
